from the beginning to the end of their lives.

and sometimes a wicked person lives long in spite of his evil deeds.

Ecclesiastes 11:8

11:8 So, if a man lives many years, let him rejoice in them all,

but let him remember that the days of darkness will be many – all that is about to come is obscure.
